A lint roller is a handheld cleaning tool consisting of a cylinder of one-sided adhesive paper or a sticky material on a handle. It is primarily used to remove lint, pet hair, dust, and debris from clothing, upholstery, and fabric surfaces by rolling it over the material. 
Key features and uses include:
Effective Cleaning: It efficiently lifts pet hair, dust, dandruff, and fuzz from fabrics and furniture.
Design: The roller usually features peel-off, disposable sticky sheets, though some modern, reusable versions use washable silicone.
Versatility: Beyond clothes, it is effective on car seats, curtains, carpets, and lampshades.
Multi-purpose: It can pick up small debris like crumbs, coffee grounds, or broken glass splinters.
Portability: It is lightweight, compact, and easy to use, making it popular for travel.
